[ic] Restore PROPERTY key tracking in keyed ICs

Non-vectorized KeyedLoadICs used to remember whether they had seen Names
as keys; Crankshaft uses this information to avoid emitting elements
accesses which would always deopt. This CL restores that functionality
for vector ICs.

All the deletions in this file were dead code anyway.
